چکیده
Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cables in the central part of the span. This is new type system for prestressed concrete bridges with longer span and has many structural features compared with ordinary cable-stayed bridge and suspension bridge. This paper reports a brief overview of construction of Nagisa Bridge with this hybrid system.

Wang and Fu 1 STATIC AND STABILITY ANALYSIS OF LONG - SPAN CABLE - STAYED STEEL BRIDGES
The analysis based on an ideal state as well as the simulation and control to reach it are common issues in the design and construction of a cable-stayed bridge. For a long-span cable-stayed bridge, the huge initial stress accumulated in the pylon and the girder will reduce the overall structure stiffness. Thus, the live load evaluation employing influence lines, which is based on the Muller-Br...

Abstract: Steel-concrete composite beam cable-stayed bridge is a complicated system consisting of a composite beam, tower, and stayed cables. And the composite beam is composed of a steel beam, bridge deck and connectors, which has a different mechanical behavior from the general beam structure. In a word, the steel-concrete composite beam cable-stayed bridge is characterized by specific mechan...
